I love the imagery provided on this.I don't know if you'll like my interpretation on the meaning, but here goes:Obviously, moths are attracted to light. This poem makes me feel like the person telling it wants someone to see how they are or how they feel, but there is someone or something, this 'moth' preventing that from happening by being too attracted to the storyteller, like maybe a love interest keeps getting turned away because of someone who is very clingy.I'm probably wrong, though.
